参考答案

正确答案：D
解析：细节题。由第四段最后一句“When a child is occupied with a computer for any length of time, that child does not get the attention of teachers and the required learning that should occupy their class time．”可知，如果孩子把 注意力集中在计算机上，他就无法关注老师，也不能集中注意力完成课堂 上应完成的学习任务，因此应选择[D]选项。其他选项与作者的观点相同。 由第三段第一句“No one will argue that computers have educational uses．” 可知，[A]选项与作者观点一致；由第三段第二句“Unfortunately, in far too many instances，the classroom computer has replaced the television set as a game tool to occupy children．”表明不应选择[C]选项。
